gnutls_x509_crt_get_fingerprint(3) gnutls gnutls_x509_crt_get_fingerprint(3) NAME gnutls_x509_crt_get_fingerprint - API function SYNOPSIS #include <gnutls/x509.h> int gnutls_x509_crt_get_fingerprint(gnutls_x509_crt_t cert, gnutls_di- gest_algorithm_t algo, void * buf, size_t * buf_size); ARGUMENTS gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t type gnutls_digest_algorithm_t algo is a digest algorithm void * buf a pointer to a structure to hold the fingerprint (may be null) size_t * buf_size initially holds the size of buf DESCRIPTION This function will calculate and copy the certificate's fingerprint in the provided buffer. The fingerprint is a hash of the DER-encoded data of the certificate. If the buffer is null then only the size will be filled. RETURNS GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the *buf_size will be updated with the required size. On success 0 is returned.
